This Sonar Display is comprised of a "waterfall," many sound waves arranged vertically. Scrolling upwards, these waves represent different sound patterns over time. Moving horizontally across the ...

Sound waves can reflect off surfaces ... This technique is applied in sonar systems used to measure the depth of the seabed and to find shipwrecks, submarines and shoals of fish.

most often sound waves. While a well-known use of this is sonar, ultrasonic sensors can also be put to use to make a radar-like system. This ultrasonic radar project is from [mircemk] who uses a ...

You can't, right? Well, not with your eyes. But you can "see" with sound waves. See how it works below, then find out what sonar is used for.

Research by the U.S. Navy has developed a new passive sonar method that could revolutionize stealth underwater drones.

To make the detection more sensitive, researchers built the phased-array sonar system. This consists of multiple units that can transmit sound waves and those of different frequencies ...

Naval sonar systems work like acoustic floodlights, sending sound waves through ocean waters for tens or even hundreds of miles to disclose large objects in their path. But this activity entails ...

Waves crash, tides go in and out ... At the heart of the “surfsonar” is the Ping Sonar Echosounder, a sonar transducer designed for AUV’s and ROV’s. [foobarbecue] embedded the transducer ...
